Nonwoven tack cloth for wipe applications

Abstract

A nonwoven web material that contains fibers formed by compounding at least one polymer with a tackifier is provided. The nonwoven web material can be used as a wipe or tack cloth and can exhibit a dust holding capacity of at least about 10 grams/m2 and a lint potential of less than about 5 fibers/cm2. In addition to containing a tackifier that is compounded with the polymer(s) used to form the fibers of the web, the nonwoven web material can be textured, post-bonded, apertured, or treated with elemental fluorine gas to further improve its dust holding capacity and minimize lint production. In addition, the nonwoven web material leaves minimal residue after contacting a surface.

What is claimed is: 
     
       1. A tack cloth comprising a meltblown or spunbond nonwoven web material, the nonwoven web material comprising fibers, wherein the fibers comprise a first polymer present in an amount of 45 wt % based on the total weight of the nonwoven web material, a second polymer present in an amount of 45 wt % based on the total weight of the nonwoven web material, and a tackifier present in an amount of 10 wt % based on the total weight of the nonwoven web material, wherein the first polymer is an olefin homopolymer, the second polymer is an olefin-based plastomer having a glass transition temperature of less than about 25° C., and the tackifier comprises a hydrocarbon resin, a polyterpene resin, a terpene-phenol resin, or a combination thereof, wherein the second polymer is present in an amount equal to or greater than the amount of the first polymer based on the total weight of the nonwoven web material, wherein the difference between the amount of the second polymer and the amount of the first polymer is in a range from 0 wt % to 5 wt %, wherein the tackifier is compounded with the first polymer and the second polymer, wherein the nonwoven web material is textured to form a three-dimensional topography, wherein the nonwoven web material has a dust holding capacity of from about 10 grams/m 2  to about 130 grams/m 2 , and wherein the amount of residue present on a surface wiped with the nonwoven web material ranges from about 0 grams/m 2  to about 0.02 grams/m 2 , wherein the tack cloth is a wipe or a glove. 
     
     
       2. The tack cloth of  claim 1 , wherein the olefin-based plastomer comprises an ethylene/α-olefin copolymer, a propylene/α-olefin copolymer, or a combination thereof. 
     
     
       3. The tack cloth of  claim 2 , wherein the olefin-based plastomer comprises an olefinic block copolymer. 
     
     
       4. The tack cloth of  claim 1 , wherein the nonwoven web material is post-bonded. 
     
     
       5. The tack cloth of  claim 1 , wherein the nonwoven web material is treated with elemental fluorine gas. 
     
     
       6. The tack cloth of  claim 1 , wherein the nonwoven web material exhibits a lint potential of less than about 5 fibers/cm 2 . 
     
     
       7. The tack cloth of  claim 1 , wherein the three-dimensional topography is formed by textured forming wires on a collecting surface that collects the fibers to form the non-woven web material. 
     
     
       8. The tack cloth of  claim 1 , wherein the nonwoven web material is apertured.
